Description

Technical Field

[0001] This invention relates to the field of testing and discloses an insulator zero-value detection device. Background Technology

[0002] Insulators are critical components in power systems, supporting conductors and preventing current from returning to ground. Insulator deterioration significantly reduces the overall insulation performance of the insulator string, necessitating regular zero-value testing. Traditional zero-value testing is manual, which is labor-intensive and dangerous. With technological advancements, drones now carry testing equipment, placing it on top of the insulator. A motor on one side of the equipment drives a probe to rotate and approach the insulator for zero-value testing. However, this type of equipment has poor stability when placed on the insulator, easily affected by wind pressure, causing swaying and vibration. This affects the contact between the probe and the insulator, reducing testing accuracy. Therefore, a more stable testing device for insulators is urgently needed. Summary of the Invention

[0003] The purpose of this invention is to provide an insulator zero-value detection device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] According to a first aspect of the present invention, an insulator zero-value detection device includes: a top frame, with downwardly extending side frames formed on the left and right sides respectively, and a detection area formed between the two side frames; a traveling mechanism disposed on the bottom side of the top frame; and a detection mechanism including a stabilizing part and a detection part disposed on the side frames, the stabilizing part having a stabilizing rod rotatably entering or leaving the detection area, and the detection part having a probe rotatably entering or leaving the detection area, wherein the detection mechanism is disposed on the two side frames respectively.

[0005] This technical solution has at least the following beneficial effects: When insulator testing is required, the top frame is moved above the insulator, and the two side frames are positioned on the left and right sides of the insulator. The top frame is then lowered, allowing the entire insulator to enter the testing area formed between the two side frames. During operation, the entire device can crawl and move on the insulator via a traveling mechanism, allowing the probe to move to the required contact hardware position. Then, the stabilizing rods of the two stabilizing parts rotate into the testing area and abut against the outer edges of the bottom sides of the insulator. At this time, the entire device forms a stable contact through the contact points between the traveling mechanism and the top side of the insulator, and between the two stabilizing rods and the contact points between the bottom sides of the insulator, ensuring that the entire device is stably positioned relative to the insulator. The probes in the two testing parts also rotate into the testing area and contact the hardware at both ends of the insulator for zero-value testing. The stabilizing rods abutting against the stable position of the outer edge of the insulator helps to ensure stable and reliable contact between the probes and the hardware at both ends of the insulator. Especially in environments with high wind pressure, it can effectively prevent the probes from swaying or shifting relative to the hardware, thus improving the accuracy of zero-value testing.

[0029] Reference Figure 1According to a first aspect of the present invention, an insulator zero-value detection device includes a top frame 110, a traveling mechanism, and a detection mechanism. Side frames 120 extending downwards are formed on the left and right sides of the top frame 110, and a detection area is formed between the two side frames 120. The traveling mechanism is disposed on the bottom side of the top frame 110 and can move on the insulator. The detection mechanism includes a stabilizing part and a detection part disposed on the side frames 120. The stabilizing part has a stabilizing rod 311 that can rotate into or out of the detection area. Naturally, the stabilizing rod 311 is made of insulating material, so it will not conduct electricity when in contact with the insulator. The detection part has a probe 321 that can rotate into or out of the detection area. The detection mechanism is disposed on each of the two side frames 120.

[0030] As described above, when insulator testing is required, the top frame 110 is moved above the insulator, and the two side frames 120 are positioned on the left and right sides of the insulator. The top frame 110 is then lowered, allowing the entire insulator to enter the testing area formed between the two side frames 120. During operation, the entire device can crawl and move on the insulator via the traveling mechanism, allowing the probe 321 to move to the required contact position. Then, the stabilizing rods 311 of the two stabilizing parts rotate into the testing area and abut against the outer edges of the bottom sides of the insulator. At this time, the entire device is connected to the top and side of the insulator via the traveling mechanism. The contact points at the position, the two stabilizing rods 311, and the contact points on both sides of the bottom of the insulator form a stable contact, so that the entire device is stably positioned relative to the insulator. The probes 321 in the two detection sections also rotate into the detection area and come into contact with the fittings at both ends of the insulator to perform zero-value detection. In this way, the stabilizing rods 311 are pressed against the outer edge of the insulator to maintain a stable position, which helps to ensure that the probes 321 and the fittings at both ends of the insulator are in stable and reliable contact. Especially in the environment of high wind pressure, it can effectively prevent the probes 321 from shaking or shifting relative to the fittings, thus improving the accuracy of zero-value detection.

[0031] In the above embodiments, the stabilizing plate in the stabilizing section and the probe 321 in the detection section can move independently. In this case, separate drive sources are needed for the movement of the stabilizing plate and the probe 321. However, in this embodiment, the stabilizing plate and the probe 321 are mutually driven, so only one drive source is needed. Specifically, the stabilizing section includes a swing arm 312, which is rotatably connected to the side frame 120 about an axis in the front-rear direction. Two swing arms 312 are spaced apart in the front-rear direction. A stabilizing rod 311 connects the two swing arms 312. The detection section includes a sliding... The slide 322 is connected to the side frame 120 in a vertical direction. The slide 323 is rotatably connected to the slide 323 about a front-back axis. The slide 322 is rotatably connected to the two swing arms 312 about a front-back axis. The probe 321 is connected to the slide 322. When the slide 323 slides downward, it can drive the stabilizing rod 311 and the probe 321 to rotate into the detection area. When the slide 323 slides upward, it can drive the stabilizing rod 311 and the probe 321 to rotate away from the detection area. In the initial state, slider 323 is at the end of its stroke. At this time, swing arm 312, carriage 322, stabilizer bar 311, and probe 321 are retracted into side frame 120. This prevents interference with the insulator when the two side frames 120 are moved to the sides of the insulator. When zero-value detection is required, slider 323 slides downward, and carriage 322 drives the two swing arms 312 into the detection area, so that stabilizer bar 311 abuts against the outside of the insulator. During the process of entering the detection area, carriage 322 drives probe 321 to the hardware position at the end of the insulator to perform zero-value detection. After completion, slider 323 slides upward, and carriage 322 drives the two swing arms 312 out of the detection area, so that stabilizer bar 311 and probe 321 rotate away from the detection area and return to the side frame 120. In this way, by providing power to slider 323, the movement of stabilizer bar 311 and probe 321 can be achieved, reducing the required drive source and helping to control the overall production cost.

[0032] In practical applications, in order to further improve the clamping force of the stabilizing rod 311 on the insulator, a structure that provides pre-pressure to the swing arm 312 can be added to the slide 322. Specifically, the slide 322 is slidably connected to a connecting part 325 along the length direction of the probe 321. The connecting part 325 is rotatably connected to the two swing arms 312. A spring 324 is connected between the connecting part 325 and the slide 322. The spring 324 has a tendency to push the connecting part 325 away from the slider 323. In this embodiment, the slide 322 is rotatably connected to the two swing arms 312 via the connecting part 325. When the stabilizing rod 311 is not against the outer edge of the insulator, the spring 324 pushes the connecting part 325 away from the end of its stroke away from the slider 323. When the slider 323 moves downward and drives the stabilizing rod 311 to press against the outer edge of the insulator, the slider 323 can move further downward. At this time, the pressure of the stabilizing rod 311 on the outer edge of the insulator is large. The pressure is transmitted to the connecting part 325, which can further deform the spring 324, causing the connecting part 325 to slide closer to the slider 323. In this way, the elastic pressure of the spring 324 is used to apply pressure to the connecting part 325, thereby making the stabilizing rod 311 elastically press against the outer edge of the insulator, further improving the reliability of the relative positioning of the insulator.

[0033] In current zero-value detection devices, the drive source is often mounted on one side frame 120. This results in one side of the device being heavier than the other, necessitating counterweights on the other side frame 120, which increases the difficulty of maintaining overall balance. Therefore, in this embodiment, a power assembly is provided on the bottom side of the top frame 110. This power assembly is connected to the sliders 323 within the two detection mechanisms, allowing the two sliders 323 to move up and down. By placing the power assembly on the bottom side of the top frame 110 and transmitting power to the sliders 323 of the two detection mechanisms, the overall center of gravity can be better controlled, maintaining the balance of the entire device.

[0034] As a specific implementation of the power assembly, the power assembly includes a motor 338, and the detection mechanism further includes a transmission unit. The transmission unit includes an upper transmission wheel 331, a guide wheel 332, a lower transmission wheel, and a transmission belt 333. The upper transmission wheel 331 is rotatably connected to the bottom side of the top frame 110 about a front-rear axis, and a transmission gear 337 is coaxially connected to the upper transmission wheel 331. The lower transmission wheel is rotatably connected to the bottom of the side frame 120 about a front-rear axis, and the guide wheel 332 is rotatably connected to the top of the side frame 120 about a front-rear axis. The transmission belt 333 is drively connected to... Between the upper drive wheel 331, the guide wheel 332, and the lower drive wheel, the slider 323 is connected to one side of the drive belt 333. The drive gears 337 in the two drive parts mesh with each other. The motor 338 is connected to either of the drive gears 337. In practical applications, the guide wheel 332 is mainly used to guide the drive belt 333 to change direction. There can be multiple guide wheels 332. For example, there are two guide wheels 332. The two guide wheels 332 are located between the upper drive wheel 331 and the lower drive wheel, respectively, to guide both sides of the drive belt 333. This allows the same motor 338 to transmit power to two detection mechanisms, further reducing the overall number of drive sources required. Specifically, the motor 338 transmits power to one of the transmission gears 337. Since the two transmission gears 337 mesh with each other, the power can be transmitted to the transmission gear 337 of the other transmission unit. At this time, the two transmission gears 337 rotate in opposite directions. While the transmission gear 337 is rotating, it can drive the coaxially connected upper transmission wheel 331 to rotate, thereby causing the transmission belt 333 to rotate between the upper transmission wheel 331 and the lower transmission wheel 332. The side where the transmission belt 333 is connected to the slider 323 is the transmission side. When the transmission side moves upward, it can drive the slider 323 to move upward. When the transmission side moves downward, it can drive the slider 323 to move downward.

[0035] The motor 338 within the power unit can also provide power to the traveling mechanism, specifically, such as... Figure 2As shown, the power assembly includes an output rod 334, a worm gear 335, and a worm wheel 336. A motor 338 drives and connects to the output rod 334. One of the transmission gears 337 is rotatably connected to the output rod 334. A first clutch assembly is provided between the output rod 334 and the transmission gear 337, which can couple or decouple the output rod 334 and the transmission gear 337. A connecting groove is formed at the end of the output rod 334, and one end of the worm gear 335 is rotatably connected to the connecting groove. A second clutch assembly is provided between the worm gear 335 and the output rod 334, which can couple or decouple the worm gear 335 and the output rod 334. The worm wheel 336 is rotatably connected to the bottom side of the top frame 110 around a left-right axis. The worm wheel 336 meshes with the worm gear 335 and is drively connected to the traveling mechanism. When movement on the insulator is required, the first clutch assembly decouples the output rod 334 from the transmission gear 337, and the second clutch assembly couples the worm gear 335 to the output rod 334. When the motor 338 is working, it drives the output rod 334 to rotate. At this time, power is only transmitted to the worm gear 335. The meshing between the worm gear 335 and the worm wheel 336 drives the worm wheel 336 to rotate, thereby transmitting power to the traveling mechanism, enabling the traveling mechanism to work and move on the insulator. When the transmission to the traveling mechanism stops, the worm gear 335... The self-locking engagement with the worm gear 336 helps maintain the traveling mechanism in a relatively stationary state on the insulator. When zero-value detection is required, the first clutch assembly couples the output rod 334 to the transmission gear 337, and the second clutch assembly decouples the worm gear 335 from the output rod 334. At this time, power is only transmitted to the transmission gear 337, providing power to the two detection mechanisms. This causes the two stabilizing rods 311 to abut against the bottom outer side of the insulator, while the two probes 321 move to the fittings at both ends of the insulator for zero-value detection. In this way, a single motor 338 can provide the necessary driving force for the movement and zero-value detection of the entire device, which helps reduce the number of drive sources and optimizes the space of the internal structure of the entire device.

[0036] As a specific implementation of the traveling mechanism, the traveling mechanism includes a pulley 410 and a track 420. The pulley 410 is rotatably connected to the bottom side of the top frame 110 about a left-right axis. Multiple pulleys 410 are spaced apart in the front-back direction. The track 420 is driven and connected among the multiple pulleys 410. A worm gear 336 is coaxially connected to any one of the pulleys 410. The worm gear 336 transmits power to any one of the pulleys 410, thereby driving the track 420 to rotate, thus enabling the entire device to move along the insulator string. The track 420 travel increases the contact area with the insulators, avoids slippage, and can distribute pressure, reducing wear on the porcelain insulators.

[0037] The first clutch assembly can be achieved by setting an electromagnetic pin inlet / outlet hole between the transmission gear 337 and the output rod 334, thereby realizing the coupling or decoupling of the output rod 334 and the transmission gear 337. In this embodiment, as shown... Figure 3 As shown, the first clutch assembly includes a magnetic shielding cover 341, a first coil 342, and a first sealing ring 343. A first annular groove is formed between the outer side of the output rod 334 and the inner side of the transmission gear 337. Two first sealing rings 343 are spaced apart in the first annular groove in a direction away from the output rod 334. The space between the two first sealing rings 343 is filled with a first magnetorheological fluid 344. The magnetic shielding cover 341 is disposed on the end face of the transmission gear 337. A first receiving groove is formed between the magnetic shielding cover 341 and the transmission gear 337. The first coil 342 is located in the first receiving groove. In practical applications, the output rod 334 can be made of a magnetic shielding material to reduce the interference of external magnetic sound on the first magnetorheological fluid 344. In order to keep the first coil 342 energized, a first slip ring can be provided on the magnetic shielding cover 341 or the transmission gear 337 to energize the first coil 342. When the power of the output rod 334 needs to be transmitted to the transmission gear 337, the first coil 342 is energized. At this time, the magnetic field generated by the first coil 342 causes the first magnetorheological fluid 344 to become a low-flow, high-viscosity fluid, which can couple the output rod 334 and the transmission gear 337 to achieve synchronous rotation of the output rod 334 and the transmission gear 337. When the power of the output rod 334 does not need to be transmitted to the transmission gear 337, the energization of the first coil 342 is stopped. At this time, the first magnetorheological fluid 344 becomes a high-flow, low-viscosity fluid, which can decouple the output rod 334 and the transmission gear 337. When the output rod 334 rotates, the transmission gear 337 remains relatively stationary.

[0038] Similarly, the second clutch assembly can be configured by providing an electromagnetic pin inlet / outlet hole between the worm gear 335 and the output rod 334, thereby achieving mutual coupling or decoupling between the worm gear 335 and the output rod 334. In this embodiment, as shown... Figure 4As shown, the second clutch assembly includes a magnetic shielding sleeve 351, a second coil 352, and a second sealing ring 353. A second annular groove is formed between the worm gear 335 and the output rod 334. Two second sealing rings 353 are formed at intervals in the second annular groove in a direction away from the worm gear 335. The space between the two second sealing rings 353 is filled with a second magnetorheological fluid 354. The magnetic shielding sleeve 351 is sleeved on the outside of the output rod 334. A second receiving groove is formed between the magnetic shielding sleeve 351 and the output rod 334. The second coil 352 is located in the second receiving groove. In practical applications, in order to keep the second coil 352 energized, a second slip ring can be provided on the magnetic shielding sleeve 351 or the output rod 334 to energize the second coil 352. When the power of the output rod 334 needs to be transmitted to the worm gear 335, the second coil 352 is energized. At this time, the magnetic field generated by the second coil 352 causes the second magnetorheological fluid 354 to become a low-flow, high-viscosity fluid, which can couple the output rod 334 and the worm gear 335 to achieve synchronous rotation. When the power of the output rod 334 does not need to be transmitted to the worm gear 335, the energization of the second coil 352 is stopped. At this time, the second magnetorheological fluid 354 becomes a high-flow, low-viscosity fluid, which can decouple the output rod 334 and the worm gear 335. When the output rod 334 rotates, the worm gear 335 remains relatively stationary.

[0039] In practical applications, the starting positions of the stabilizing rod 311 and the probe 321 can be adjusted according to the insulator type. Specifically, for example... Figure 5 As shown, the swing arm 312 can move and be positioned vertically on the side frame 120. In practical applications, an adjustment block that can be locked and positioned by bolts or pins can be provided on the side frame 120, and the swing arm 312 is rotatably connected to the adjustment block. By adjusting the adjustment block vertically on the side frame 120, the height of the swing arm 312 can be positioned. After the swing arm 312 is moved upward and positioned on the side frame 120, the height of the stabilizer rod 311 and the probe 321 in the initial state of rotation can be raised. Conversely, after the swing arm 312 is moved downward and positioned on the side frame 120, the height of the stabilizer rod 311 and the probe 321 in the initial state of rotation can be lowered. This enhances the adaptability of the entire device and better accommodates the use of various circuits.

[0040] The top frame 110 can be directly equipped with flight propulsion components such as propellers, or with components that are convenient for mounting on a drone. Specifically, a sling 500 is connected to the top side of the top frame 110. The drone can be connected to the sling 500 via a sling, thereby enabling it to be mounted on the drone.
